i have a 2004 le with 27000 miles on it. the clamp on the tail pipe has rotted through ruining the pipe and the muffler. this truck is driven in winter [salt] but constantly has the undercarriage washed. i am 5 months out of warranty and basicaly nissan says to bad. anybody else have this problem? when at the dealership they said very common along with the manifolds cracking. was going to keep this truck for quite sometime but i must say the yota is looking better. at least the yota dealer will push for me. has in the past.
